Abstract:
A self-lubricating, friction and wear reducing composite material for use over a wide temperature spectrum from cryogenic temperature to about 900.degree. C. in a chemically reactive environment comprising silver, barium fluoride/calcium fluoride eutectic, and metal bonded chromium carbide.
Abstract:
Agent for the pickling of and as an antioxidant for workpieces made of iron and steel in the case of when they are subjected to non-cutting, hot transformation. The agent is used in dry form. The agent contains: (a) 20 to 80 percent by weight of a pickling-effective compound, such as, sodium metaborate; (b) 1 to 80 percent by weight of a component, such as, graphite; and (c) zero to 79 percent by weight of at least one substance selected from group (d), (e) and/or (f). Zero to 35 percent by weight of group (d), such as, coke, can be used as substance (c) and, for example, act as antioxidants. Zero to 50 percent by weight of group (e), such as, sodium chloride, can be used as substance (c), and control the physical characteristics. Zero to 5 percent by weight of group (f), such as, ammonium chloride, can be used as substance (c) and, for example, act on the reduction of the oxides of group (a).
Abstract:
A plain bearing of the trimetal type wherein the antifriction layer is of an alloy with a Pb-Sn-Cu base, having a copper content from 2 to 6% by weight, a tin content from 8 to 13% by weight and the remainder being lead, the said alloy being added with an amount of carbon fibers, the alloy and carbon fibers being electrochemically deposited. The carbon fibers exhibit a random arrangement within the metal matrix and the fiber tips emerging from the alloy are embedded in the adjoining layer.
Abstract:
A water-based lubricant is provided that includes a phthalate ester in an amount of about 2 % to about 20 % based on the weight of the final composition and water in an amount of about 60 % to about 93 % based on the weight of the final composition. Also provided are a method of making the water-based lubricant and a method of metalworking using the water-based lubricant.
Abstract:
A lubricant coating disposed between a substrate and a counter surface comprises a reaction layer immediately adjacent the substrate. A bonding layer is immediately adjacent the reaction layer, with the bonding layer comprising a first composition. A low friction, lubricious layer is immediately adjacent the bonding layer, with the lubricious layer comprising a second composition that is different from the first composition.

Abstract:
The invention concerns a composition for preparing metal products designed to be shaped by at least one mechanical process of plastic deformation such as wire drawing, rolling, calendering, forging, swaging and the like, without notable shrinkage of substance. The invention is characterised in that it comprises a film-forming binder, at least an additive reactive with the metal, at least a lubricating additive and at least an anticorrosive additive. The invention also concerns a method for preparing said metal products using the claimed composition.
Abstract:
A solid lubricant additive for resin-bound friction lining mixtures is characterised in that it contains a combination of copper-I-sulphide (Cu2S) with at least another sulphide of molybdenum, zinc, antimony, wolfram, tin and/or titanium.
Abstract:
A rubber or plastic sliding member coated with a material having excellent durability and high slipperiness, wherein the coating material is composed of a solid lubricant such as molybdenum disulfide and a resin matrix comprising a fluoroolefin vinyl ether polymer resin and/or a fluoroolefin vinyl ether/vinyl ester copolymer resin.
